Alexandre,
thanks again for your help.
The event is not triggered with the code you posted so I changed a few
things around, though it's probably not the best way to do this, and it
seems to be triggered:
var oDrawPoint = new OpenLayers.Control.DrawFeature(vectors,
OpenLayers.Handler.Point);
vectors.events.on({'
featureadded': onPointFeatureAdded, 'scope': oDrawPoint });
function onPointFeatureAdded (event) {
var feature = event.feature;
if (feature.geometry.CLASS_NAME ==
'OpenLayers.Geometry.Point') {
var symbolizer =
feature.layer.styleMap.createSymbolizer(feature);
feature.style = symbolizer;
feature.style.externalGraphic =
\"images/markers/marker-gold.png\";
feature.style.pointRadius = 13;
feature.style.fillOpacity = 1;
feature.layer.drawFeature(feature);
}
}
Though that if statement there must be surely incorrect but I wasn't able to
trigger the event of a point added any other way.
On to figuring out the different images now!
Thanks,
Alex
